Stick Coil Removal/Installation

• Refer to the Stick Coil Removal/Installation in the Electrical System chapter.

Stick Coil Primary Winding Resistance Inspection

• Refer to the Stick Coil Inspection in the Electrical System chapter.

  If the reading is within the standard, check the input voltage (see Stick Coil Input Voltage Inspection).

Stick Coil Input Voltage Inspection

NOTE

• Be sure the battery is fully charged.

• Turn the ignition switch OFF.
• Remove the ECU (see ECU Removal).
  • Do not disconnect the ECU connectors.
• Connect a digital meter [A] to the connector [B] with the needle adapter set.

Special Tool - Needle Adapter Set: 57001-1457

Stick Coil Input Voltage
 Connections to ECU Connector:

For Stick Coil #1
 Digital Meter (+) → BK lead (terminal 40)
 Digital Meter (-) → BK/Y lead (terminal 54) For Stick Coil #2
 Digital Meter (+) → R/W lead (terminal 47)
 Digital Meter (-) → BK/Y lead (terminal 54) For Stick Coil #3
 Digital Meter (+) → BK/W lead (terminal 39)
 Digital Meter (-) → BK/Y lead (terminal 54) For Stick Coil #4
 Digital Meter (+) → BK/O lead (terminal 38)
 Digital Meter (-) → BK/Y lead (terminal 54)

• Measure the input voltage to each primary winding of the stick coils with the engine stopped and with the connectors joined.
• Turn the engine stop switch to run position.
• Turn the ignition switch ON.

Input Voltage
 Standard: Battery Voltage

• Turn the ignition switch OFF.

  If the input voltage is out of the standard, check the wiring for continuity (see wiring diagram in this section).

  If the wiring is good, check the ECU for its ground and power supply (see ECU Power Supply Inspection).

  If the ground and power supply are good, replace the ECU (see ECU Removal/Installation).

  If the input voltage is within the standard, check the ECU for its ground and power supply (see ECU Power Supply Inspection).

  If the ground and power supply are good, replace the ECU (see ECU Removal/Installation).
